摘　　要：采用热水浸提法提取白酒丢糟中的低聚木糖,利用单因素试验和正交试验确定了最优提取工艺条件为:温度100℃、料液比1︰20(g/m L)、提取时间120 min;乙醇萃取试验表明95%乙醇效果最好,提取率达91.57%;质谱结果表明低聚木糖中主要含木五糖、木七糖和木三糖。The xyol-oligosaccharides were extracted from distiller＇s grains of liquor by hot water. And the optimal process condition was got by single factor experiment and orthogonal test, the temperature, solid-liquid ratio, and extraction time was 100 ℃, ratio of material to liquid 1︰20（g/m L） and extraction time 120 min respectively. And 95% ethanol was the best with the high yield of 91.57%. The xyol-oligosaccharides were mainly constituted of xylopentaose, xyloheptaose and xylotriose by mass spectrometric analysis.
